Please hold off on getting any parts replaced.

(1) Power the PC off, disconnect the PC power cord from the rear of the PC, open the case cover. Look for the screws holding the H2C cooling unit (8) to the motherboard. Tighten these. Were your screws loose? Replace the cover and power the PC on.

  • Hi,


    I seem to have fixed the issue for random reboot on 730x H2C by making the changes in BIOS and un-installing thermal app.  Dell contractor onsite did all 3 items including checking for loose screws on cooling unit.

    I still have problems sometimes doing a cold boot where the machine will just hang with fans spinning on high.  Another post I found seems to get around the issue, by holding reset button while turning on power button, then releasing reset button.

    Now, machine is fairly stable, but my games are crashing.  World in Conflict and GTA IV are crashing on me.  I have run the pre-assesment test while rebooting pc and that is ok.  Also checked directx 10 tests via dxdiag and that is ok.  I have dual nVidia 9800GT's.  I'm running Vista x64.


    Also, I cannot run the diag CD when rebooting - I get Drive F: Driver "Extcd001' unit 0.  batch file F:\dosmenu.bat missing. I wanted to run some other tests from the tree.  I had wiped out all partitions when setting up my raid 1, but Dell tech support over phone did not tell me to re-setup any kind of utility partition.

  • Oh, one more thing.  Dell wanted to throw a new motherboard, memory, cooling unit at the issue, but I cancelled my dispatch.  I went through this with my 720 H2C last year and I know from reading the posts online that this issue with 730x seemed to be more around BIOS/motherboard/overclocking. Any idea when the Corsair DDR3 6 GB tri-channel will be available from Dell?  I need to trade in my old Corsair DDR2.

  • Ben_H2C_730x,

    Disable SLI and check the games.
